I think 5zigen and Crazy Vitz makes a bigger throttle body for the Vitz...which has the same engine as the xA/xB.

k thank you i will look into that

You may gain some top end power, but you'll lost some low end torque. Just be prepared for the outcome is all. Good luck on your search and keep us updated!!
